Effect of isolated ultrafiltration and isovolemic dialysis on myocardial perfusion and left ventricular function assessed with ~13N-NH_3 positron emission tomography and echocardiography

摘要

Hemodialysis is associated with a fall in myocardial perfusion and may induce regional left ventricular (LV) systolic dysfunction. The pathophysiology of this entity is incompletely understood, and the contribution of ultrafiltration and diffusive dialysis has not been studied. We investigated the effect of isolated ultrafiltration and isovolemic dialysis on myocardial perfusion and LV function.
